Application led March 2, 1917. Serial No. 152,047.

To all whom t may concern:

Be it known that I, FRED A. KAEDING, a citizen of the United States, residing at Kramer, in the county of Bottineau and State of North Dakota, have invented new and usefullmprovements in Hay-Stackers, of which the following is a specification.

This invention relates to hay stackers of that general class or type which embodies a frame structure, a load carrier and means for elevating the load carrier and for tilting the same to discharge the load in the desired direction, the load being placed on the carrier by a bull rake of ordinary construction.

The present invention has for its object to y produce a device of the class specified wherein the load carrier will be guided for movement in a vertical plane instead of in an yinclined `plane as is customary, it being :found that economies may thereby be effected in space, Vstructural material andin p ower required forthe operation of the dey vice. A further object of the invention is to simplify and improvefthe general construction and arrangement of the frame structures including the tracks on which the load carrier is uided. y

` further object of the invention is to simplify and improve theconstruction and operation of the load carrier and the means whereby the same may be tilted to a discharging position at the required point of its upward movement. l

With these and other ends in view which will readily appear `as the nature of the in-r vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described-y and particularly pointed out inthe claims.`

In the accompanying drawings has been illustrated a simple and preferred form oi the invention, it being, however, understood that no .limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

1n the drawings, 1 v

Figure 1 is a view in front elevation of a hay stacker constructed in accordance with the invention7 the load carrier` being shown at the lowerinost limit of its movement.

Fig. 2 is a, sideelevation showingy the load carrier atthe upper limit of its movement andin a tilted or discharging position.

Fig. 3 is a rear elevation showing the load carrier in an intermediate position.

Fig. 4 is a top plan view showing the load carrier in its initial or receiving position.

Fig. 5 is a vertical sectional detail view taken on the line 5 5 in Fig. 1.

Fig. 6 is a sectional detail view through one of the upright track members and a portion of the load carrier, the saine being taken on the line 6-6 in Fig. 2. f

Fig. 7 is a perspective view illustrating a inodiiied form of the tilting mechanism.

Corresponding parts in the several iigures of the drawings are denoted by like characters of reference. p

The base or supporting frame of the im,- proved machine has been shown as being composed of longitudinally disposed sills 15, the same being spaced apart and connected together by cross bars 16, said sills andcross bars consisting of timbers of suitable dimensions to aftord a support `of the requisite strength and superlicial area to firmly sustain the'working parts of the frame in position for operation. The sills and cross bars are preferably mortised together at their re-` spective points of intersection, and are bolted or otherwisel firmly secured together. The longitudinal sills 15 have been shown as being equipped at the front ends thereof .p with ground engaging wheels 17 to facilitate the moving of the machine from place to place. The baseframe has also been shown as being equipped with rings or eyes 18 Sil through which stakes may be driven for the f purpose of anchoring the frame in position for operation.

Supported on the base frame and eXtending upwardly therethrough are two track bars 19, said bars :being disposed vertically and in spaced parallel relation. These track bars may consist of rods, tubular or otherwise, the lower ends of the same being externally threaded anditted in correspondingly flanged sockets 20 of Hoor flanges 21 which are bolted or otherwise secured onthe base frame, this form of construction avoiding the weakening of the base frame by mutilating the same to receive the lower ends of the track bars. The upper ends of the track bars are connected together and rspaced apart by a cross bar-or cap piece 23, the same' being secured in position byineans of nuts 24 for the reception of which theupper ex-Y tremities of the track bars are externally threaded. Guy rods or .braces 25 lconnect the upper end portions Yof the track bars with the base frame with which the lower extremities of said guy rods or bracesare suitably connected, preferably in such* a manner as to enable themto be properl T tensioned and adjusted to sustainthe trac t bars in an upright lor vertical position. I

i The load carrier comprises in its construction a pair of sleeves 26 slidably mounted on the track bars, said sleeves being provided at their lower ends with L-shaped coupling members 27 having laterally extending sockets 28, saidl sockets aiording supports ,for a transverse shaft 29 whereby the coupling members 27 as' well as the sleeves 26 are connected together and spaced apart in such a manner as to be freelto move vertically on the track bars 19. lThe load carrier further includes a bottoin'platform 30 and a rear wall or platform '31, said platforms being each composed of a plurality of teeth or fingers 32- andrl, preferably made y"of wood, the same being securely mounted on, metallic frame structures 34 and 35. The respective platforms are of less width'than the distance between the upright track bars, but the frame structure 35 of the rear wallor platform k31 includes" across bar`-36 which is of suilicient length to abut' terminally on the rear faces 'of the sleeves 26. The frame structurey of the rear wall or ,platform 31 is provided with bearing sleeves 37 pivotally engaging the shaft 29, the cross-bar 36 serving as aforesaid to limit the swinging movement in al forward direction of the wall or platform 31.V The cross-bar 36 is connected with the frame structure of the bottom `platform `30 by means of inclined braces 88 whereby the rear wall or platform will be sustained in la, position at an angle exceeding ninety degfress with respect to the bottom platform 30, which latter', in its normal or load receiving'position, occupies an approximately horizontalposition as will be best seen in. Fig. 1 of the drawings. SpringsV 39 are coiled lon the shaft' 29, eachv of said'springs Y being terminally connected at one end with the kshaft and at the other end with the frame structure of the rearl wall or platform 31,`th`e tension lof said springs being vexerted to maintain said rear ywall or platform ink an -'upright position with the ends of the cross bar 36 in engagement with the rear' sides of the sleeves 26. f l v K Flexible hoisting elementsA such as ropes or :cables 40, two in number, areprovided, each of said elements being terminally connected at one end withthe bottom platform n* ofthe loadcarrier, Ynear ythe rearward end4 thereof. The hoisting elements arel guided over pulleys 41 which :haveI been shown. as ybeing suspended near the uppery extremities of the track bars 19, the hoistingelementsbeing subsequently guided over pul'leys`42'w'hich' are mounted near the lower extremities of the track bars. The hoisting -f Velements are subsequently joined together f and connected with a draft element which has been shown as consisting of an ordinary evener or swingle tree 43.k

44 designates an element which I call a f tilting frame, the same consisting of a frame made of a rod or wire in approximatelyy trin angular shape, the same having two limbs one of which, 45,y is provided with an eye 46 ypivotally engaging the shaft 29. The other limb 47 of the tilting frame is connected with the frame vstructure of the rear wall or platform of the load carrier. The tilting frame is formed intermediatek the limbs and 47 with ay plurality' of loops '48,`r said loops beingl disposed lonev above the other in a vertical plane. Connected with the base frame isl one end of a tilting rope 49,` said rope having a plurality ofstop members such as knots k50 whichy may be formed or secured thereon'at` suitable intervals. This tilting k.rope is to'be adjusted in one of the loops 48 of the tilting frame where, `by reason of thestop members 50, it

will be held securely in any' position to which it may be adjusted. The'tilting rope cooperates with the tilting frame to tiltv the load carrier from its normal or receive ingipositionrto a discharging position ata predetermined point of the upward movement' of said load carrier, itbeing'readily,

understood'that when the tilting ropey becomes tensioned it will exert a downwardv pull on' the ytilting frame, thereby causing the platforms ofthe load 'carrier to be tilted above the axis of the shaftf2`9 until' the" load receiving platform 30 'occupies VA'a substantially vertical position 'while the wall or platform 31 will be'til'ted in a'down'ward' and rearward direction as clearly fseenjin Fig. Q of the drawings, thus causing .the load toslide from the load carrier inthe direction ofthe stack.v By proper adjust'- ment of the tilting 'ropewith respect to the tilting frameit will be seen that 'the Adis- Sti lic

chargingoperation may rbe performed at any predetermined point -of thefoutward movementk ofY the load* ca rrieng'therebyv avoiding the necessity `of, lifting* -'t-h'e load beyond the point -absolutelynecessary to insure the proper discharge ofthe load' on 'the` stack which is in Vprocess 'of formation. lt will also beseen "that 'agvery minute adjust ment may be effected owing to ithejpresence of a plurality of loops 48' Iin the vtilting frame 'and afplurality of knots orstop members on the tilting rope, vthe rope being shifted" from one -loop ltoanoth'er of the tilting frame -before passing 'to the "nextv c knot or stop? member, therebyy `avoidingthe encumbering of the tilting rope with a large number of knots.

Instead of using the tilting rope 49 having stop members such as knots 50 it may be found desirable to use a chain such as illustrated in Fig. 7 where said chain is designated by 55, one end of said chain being connected with one of the loops 48 of the tilting frame 44. On the base frame there is provided a latch device such as a snap 56 with which one of the links of the chain 55 may be detachably connected, thereby enabling the operator to effect the desired adjustment in a very convenient and satisfactory manner.

From the foregoing description, taken in connection with the drawings hereto anneXed, the operation and advantages of the improved hay stacker will be readily understood. It will be seen that owing to the vertical positioning of the track bars a machine may be constructed occupying much less superficial area than machines that are provided with inclined tracks. Considerable economies in structural material are also effected, and it will be found that the machine may be operated with slight expenditure of power. The machine may also be conveniently moved from place to place, and it is capable of being stored in small comass.

P Having thus described the invention, what is claimed as new is:

1. In a machine of the class described, the combination with a pair of vertical track bars, of a load carrier mounted thereon for vertical movement, said load carrier comprising sleeves engaging the track bars, coupling members at the lower ends of said sleeves having laterally extending sockets, a shaft secured in said sockets, a tiltable element comprising a receiving platform and a discharging platform secured together in angular relation, said discharging platform having bearing members engaging the shaft and a cross bar that engages the sleeves to limit swinging movement of said platform in a forward direction, and a spring whereby the discharging platform 'is normally swung ina forward direction thereby positioning the receiving platform in a receiving position.

2. In a machine of the class described, a pair of vertically disposed track bars arranged in spaced parallel relation, a load carrier mounted for vertical movement on said track bars, said load carrier including track bar engaging sleeves, coupling members at the lower ends of the sleeves, a
